Looking for Moultries of Fife/Aberdeenshire

I am interested in any information about the Moultrie family from Fife, Scotland. My gg-grandparents were George MOULTRIE & Catherine ALLAN. They lived in the village of Saline. George & Catherine had 4 children: William, Christina, Marion & James. James, was my great-grandfather & he was killed during WWI. (George had an earlier marriage to Christian (or Christina) KEIR.) A complicating factor has been the fact that George was illegitimate. His mother, Margaret HUNTER never married. I know his father's name was also George Moultrie. My great-grandfather James married Mary Richardson O'BRIEN from Burghead, Morayshire. They shifted to Aberdeenshire about 1910.
